1. Which of the following organs is NOT directly involved in the mechanical breakdown of food?

• A. Mouth
• B. Stomach
• C. Small intestine
• D. Esophagus

Correct answer: D

Rationale: The correct answer is D, esophagus. The esophagus is a muscular tube that connects the mouth to the stomach, but it is not directly involved in the mechanical breakdown of food. The mouth is responsible for the initial mechanical breakdown of food through chewing, the stomach further breaks down food through muscular contractions, and the small intestine aids in the digestion process. However, the esophagus primarily serves to transport chewed food from the mouth to the stomach via peristaltic movements, without actively breaking down the food itself.

While an organ is made up of different types of tissues that work together, an organ system involves multiple organs collaborating to perform more complex tasks. Tissues (option A) are groups of similar cells working together, organelles (option C) are structures within cells that have specific functions, and organs (option D) are made up of tissues and perform specific functions, but the term 'organ system' specifically refers to a higher level of organization involving multiple organs working in coordination.

5. Which neurotransmitter is associated with mood, sleep, and memory?

• A. Dopamine
• B. Serotonin

Correct answer: B

Rationale: The correct answer is B: Serotonin. Serotonin is a neurotransmitter that plays a crucial role in regulating mood, sleep, and memory. It is known as the 'feel-good' neurotransmitter because it helps to promote feelings of well-being and happiness. Serotonin also contributes to the regulation of sleep patterns and plays a role in memory and learning processes. Dopamine is associated with reward and motivation, acetylcholine with muscle movement and cognitive functions, and glutamate with learning and memory as an excitatory neurotransmitter. Therefore, of the options provided, serotonin is the neurotransmitter most closely linked to mood, sleep, and memory.

This is evident in the scenario where the former manager showed passion for serving her staff. Servant leaders are known for their humility, empathy, and commitment to the growth and well-being of their team. This leadership approach fosters a positive work environment, builds trust, and promotes collaboration among team members.
